When my fiancé was in high school, one of his childhood friends (his best friend) committed suicide.  My fiancé was devastated by his death and had difficultly coping, but came to accept it after time.  He graduated from high school, and from there began commuting to a local university for college courses.  During this time, he received an odd phone call late at night (He says it was around 1 o'clock in the morning).  My future father-in-law answered the phone, and upon hearing that it was for my fiancé, handed him the receiver.  My fiancé claims that it was his deceased best friend calling, and talking to him as if nothing had happened.  He greeted my fiancé by saying, "How are you doing, man? We haven't talked for a few years.  What's been going on?”  The conversation took place as a normal conversation between friends would, and they both said their good-byes.  Afterwards, he was frightened and has not mentioned it to anyone except myself since.  He insists that he heard his deceased friend's voice distinctly over the phone, and has not gotten any more calls such as this.  As far as I know, he did not inquire about his friend's location or why he had called.  Nevertheless, he was disturbed by the call and swears that he telling the truth.  I am inclined to believe him, as he is not one to weave false tales or trivial ghost stories.
